How Long Does Propecia Take to Dissolve in the Body?

Upon taking propecia, how long before it dissolves and enters the bloodstream? Better yet, how long will it be before it is safe from urination or involuntary regurgitation of food?

Thanks doc

Propecia (finasteride 1mg) will go through an empty stomach in under an hour, but if the stomach is full of food, well that relates to the emptying time of the stomach which will vary based upon so many factors that there is no real answer to that part of your question. It will last about 24 hours in your body, dropping blood levels at about 50% for every 4-6 hours after it is absorbed. If you were to vomit, it would depend upon what you had in your stomach when you took it. An empty stomach will absorb it very quickly.

I don’t quite understand the uriniation part of your question, but you will not pass it through your kidneys as finasteride, but rather as the metabolites of that drug. Wikipedia says the excretion of finasteride is feces (57%) and urine (39%) as metabolites, but I do not how accurate that is, nor do I quite know what that means, since the drug is metabolized on its pass through the liver if it does not get absorbed as finasteride directly from the blood stream. Long story short, I don’t believe you should worry about passing it through your bladder if that was your concern.
